how to get a registered adapter name

how to get a registered adapter name

[Benedict bdc091]

Hi list,

I'd like to enumerate connected DVB devices from my softawre, based on
DVB API V3.
Thank to ioctl FE_GET_INFO, I'm able to get frontends name, but they
are not "clear" enough for users.

After a "quick look" in /var/log/messages I discovered that adapters
name are much expressives:

> ...
> DVB: registering new adapter (ASUS My Cinema U3000 Mini DVBT Tuner)
> DVB: registering adapter 0 frontend 0 (DiBcom 7000PC)...
> ...

So, I tried to figure out a way to get "ASUS My Cinema U3000 Mini DVBT
Tuner" string from adapter, instead of "DiBcom 7000PC" from adapter's
frontend...
Unsuccefully so far.

Any suggestions?


Regards

Hello,

I have the same issue, I look a bit to the code of the DVB drivers, it
seems not obvious to recover this name as it is written now

It is stored in the "struct dvb_adapter". and printed by
dvb_register_adapter, but doesn't seems to be available by other functions

I don't think changing the v3 API or adding a new IOCTL for this is a
good idea.

What about using the new DVB API (v5) to do this? Since I'm not an
expert with this API, is there some people familiar with it which can
give me advices about the good way to do it (and if it is a good idea)
so that I can start to write some code.

Thank you

Regards

I think putting it somewhere into sysfs is a good idea (along with frontend 
name).
Best is to move all dvb sysfs-devices into a per adapter subdirectory.

Hello

Is there already parts of the DVB code that use explicitely sysfs ?

I pehraps missed something, but it seems that everything in sysfs
concerning DVB is coming from the subsystems (PCI, or USB) or the
modules parameters but no DVB wide information

Am I wrong ?

Is there a reason for this ?
